The Amphibian Oasis

A salamander's skin is its lungs, its kidneys, and its biggest vulnerability, which makes the water in its tank a life-support system rather than decoration. This course teaches you to run that system. You'll learn why pH should sit steady between 7.2 and 7.8 and what general and carbonate hardness do, how the nitrogen cycle turns ammonia into nitrite and nitrate and why a new tank runs empty for four to six weeks first, why untreated tap water is a chemical burn and what a conditioner like Seachem Prime does, why a rushing power filter exhausts a clumsy swimmer and how a sponge filter or a baffle fixes it, why water above 74°F crashes an immune system and how chillers and evaporation fans hold the 60 to 68°F range, how a fully aquatic tank differs from a paludarium or a damp forest-floor enclosure, how cork-bark ramps and tethered rafts prevent drowning, why land soil should feel like a wrung-out sponge and why reptile carpet is banned, why small gravel is swallowed and fatal and large river stones aren't, which plants survive low light, why earthworms are the staple and how often an adult actually eats, how to spot a chubby newt, why bare hands strip the slime coat and wet nitrile gloves don't, what an eft is and how it finds its way back to water, how to rearrange a tank so it stays interesting, how to do the daily four-point scan and set up a hospital bin, what to do the minute ammonia spikes, and how to find a vet through the ARAV directory before you need one.
